Adisk with a radius of r is oriented with its normal unit vector at an angle θ with respect to a uniform electric field. which of the following represent the electric flux through the disk?

The electric flux through the disk are

Explanation:

Electric Force is Calculated by:

Electric flux = E * A cosθ

where

E is the magnitude of the electric field

A represent area of the disk

and θ is the angle between the electric field lines and the normal (perpendicular) to A

Area, A = πR²

So, Electric flux = E(πR²) cosθ

Also, note that the cosine of an angle can be written as sine of its complementary angle.

Assuming θ + ϕ = 180

Then,  cosθ = sinϕ

So, Electric flux = E(πR²) cosθ can be written as

Electric flux = E(πR²) sinϕ

it doesn't. it was imagined up in the middle ages.

that would be because of both gravity and friction. so     c
